.No r/// frito/)t it 12mg/ concer/7,:

Bc it known that I, CHRISTIAN H. Cnnis- "rmxsox, a citizen of thc United States, residing atChicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements ,in Antifriction- Bearings; and l do hereby declare the following to he a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and ilse the saine.

My invention relates to an antifrictionbearing; and it consists of certain novel features of combination and construction of parts, the preferred form or materialization whereof will be hereinafter clearly set forth, and pointed out in the claims.

The prime object of my invention, among others, is to provide a bearing of the charac ter specified which while primarily designed as a bearing for car-axles will also be found reliably efficient and desirable for all manner of bearings, as upon freight and assenger cars, locomotives, automobiles, an ,in fact, all variety of vehicles where it is desirable and necessary to reduce the friction incident to use of the journals or traveling wheels to a minimum.

Other objl ects and advantages will be hereinafter made clearly apparent, reference being had to the accompanying drawings, which are made a part of this application, and in which-i Figure l is a side elevation of my invention as applied to use upon a car-axle, the casing surrounding the end of the journal or axle being shown in section. Fig. 2 is a longitudinal central section, as indicated byline 2 2 of Fig. `l. F ig. l is a sectional view of my journal'hox or bearing, taken on line 3 3 of, Fig. 4 is a sectional view of Fig. Ii

Pig. l. I l y taken on line 4 i, the direction of the arrows indicating `the viewpoint. Fig. 5 is a sectional view of part of inyinvention, taken on line 5 5 of Fig. 3. Fig. 6 is adetail View showing one of the means which may be adopted in connecting the pluralit of antil'riction wheels or rollers employe near the outer end of the journal-box. Fig. 7 is a detail view, pzirtly in section, indicating means of connectin' the antifriction wheels or roll-` ers employe in cooperation with the journal and provided in multiple to cooperate with that part of the journal within the journal boxf or housing. Fig. 8 is a detail view of part of the construction illustrated in Fig. 7 and other views. Fig, 9 is a perspective view showing an intermediary or antifriction device employed to se arate the. antifriction `devices cooperating irectly with the end of the journal and the walls .of the journal-box. Fig. 10 is a detail sectional view, on an enlarged scale, of a portion of the antifi'iction device assembled. A

For convenience of reference to the various details of iny invention and coperating^a 2- cessories numerals will be employedtlie same numerai applying t af similar part throu hout the several views.

Re erring to the iiuinerals'on the drawings, l indicates the end of the journal, while 2 indicates the journal-box proper, botli ol' which may be constructed, substantially,in the usual manner, the said journalsbox being designed as a housing for the bearing portion or outer. end of the journal, as is common, the said box bcing connected with `the su porting-trucks or carrying-rame inthe usua well-known inanner, and I therefore deem it unnecessary to specifically refer thereto.

The journal-box 2 is rovided with the lid or closui'e section 3, w -ch' is held in union with the 'ournal-box propel" in any preferred way, as y the screw-bolts 4 or equivalent. means. The middle portion of the lid or closure section 3 is provided with a swell or extension, as indicated by the numeral 5, and to this swell or extension I secure the lubliant boar or receptacle 6, as by the serewbolts 7, the said lubricant-box having, as is 'eommonftlie nornialiy closed lid 8, while a communicating duct or bore il is also formed in the swell extension 5, said duct or bore leading into the interior of the j ournal-'box to insure that a proper supply of lubricant will pass by capillary attraction through the roll of waste or the like l() and thence dro i down ward into the duct 9, as will be un erstood by reference to Fig. 1.

and designed to Cof the liournal are the fiction wheels or rollers or equivalent devices l, nrranged in overlapping s fries or groups, wher. ly thrY plurrlitv ol rollers will be disp-med in staggered relationship, as will he observed by reference to Fig. l. The said ani/itriotionm rollers are loosel)r mounted upon the carrying-shafts ln the present application lhave "lustrate-(l in Fig. 1 each alt :ne shaft es being oroviried with lr-lsorrollhv only two aiitifrietion-Wh .Us understood that this arra nt mav be Varied and any desirel nuiooor of sntirrietion-wheels disposez-.rl upon eafoh alternate shaft, wherel'if said .a'lieels will he located so that. the wheels carried one shalt will partly ofnlap the Wheels of the next adjaor it shex liereif-t inst l that tho greatest possible ainounl' ot oor-ri url'aoe will he alforded 'tor 'the ol tli al l, it being understood. that the diameters of the anti- .lriotion rollers or wheels il are 'the saine and are or" suoli extent to reach into engage nient with the periphery ol the journal 1 and a eontig-fsf.,-llA el the easing or journal-v obvious thst the antifriotion devices or wheels l ere designed to support the load, and it therefore ollovfs that said devices, together with the easing or journal-hos; 2, shall be formed orn suitable material affording the re# j. qulsite strength.

lt will be observed by reference to Fig. 1 that the journal l passes loosely through an openingY lin the inner end of the journalboi, whereby said journal will not engage the Walls of the` box incident to the use thereof. 'llo provide against an end thrust of the jour nal, whereby it will Contact with the closure or lid section 3, l utilize the space on the inner side of the swell or extension in order to mount suitable antifriotion-rollers, as indicated by the numeral 19, said rollers being rotatably supported upon the shaft 20. The antilriotion rollers or wheels 19 are properly spaoed that they will engage the end of the journal upon opposite sides of the axial plane thereof', and by reference to Figs. 2 and 3 it will be observed that the shaft 20 is seated in suitable hores rovided in the semioollar members 21 an 22, the ends of said collars being overlap ed on each other, as shown in Fig. 5, wherellijy the outer edges thereof will. he left flush with etch other, said overlapped portions being looked in permanent union with each other, as by the clamping screws or bolts 23. The shaft 20 is reinforced and sustained in its central portion by an auxiliary shaft 24, whieh is provided in its oeny tral part With an. enlarged, preferably squared section 25, integrally formed with said shalt mo or otherwise connected thereto, as by providing parts having suitable recesses and seating the shaft 24 therein andloeking the parte together, as by the set-screws 26. The outer ends of the shaft 24 are received he- 105 tween the overlapped ends of the semioir eular Collar members 21 and 22, as illusu trated in Fig. 5. The periphery of the eollar members 21 and 22 is shaped to provide a continuous groove therearounrl, and within rie said groove is designed to travel a plurality of antiiriotion-wheels 27, said Wheels being oonneoted with each other in a continuous chain, as oy the side bars 28, properly shaped their meeting ends and connected to- 1x5 ther, as by the bolt or rod 29 or other nivalent means. Each of the side bars 28,

ill oe understood, is provided With a suitlel aperture designed to register with an a ierture or bore in the antil'riotion-wheel 27, 12o Wnehy the rod or axle may he mounted j in the proper place, whereby the side hars will be connected with the wheel between '-liein and permit said wheel to freelj,7 rotate incident t'o use. i'

Ey reference to Fig. 2 it will he observed that the extreme outer end of the journal l provided with a radial llange or edge 3l, ,eh will tend to confine the entitriotion- Wheels their proper places within the hous- 15o ing. the swaying motion of the car will cruise the untirietion-wheels 19 to bear against the. end 0l the axle and a Contiguous part of the inner wall of the swell or extension thus ineuring that :a riuniniuni-nmount of friction will result Each end of each alternate shaftl2 is sented in n seniispherical member 32, while remaining shaft is journuled into n linlt-secti0n 33, sti-id sernisi'iherical ineinbers and linke being pivottillv united..v as b r rivets or bolts 34, whereby a continuous chain will be formed supplementing the intermediate connections cooperating with said Between the seznisnhericn members; 32 and the contiguous untilriotiow ljl l .locate the collnr-liko members '35,hovlng the outwnrdlyeefttending lugs or pintles 36, upon which l rotatnblv secure the un tifrie tion-wheels il?, correspon ing in funetion with the-:tntifriction devices l?, the saine being designed to bear against a part of the contiguous ant-ifriction-wheel ll. will be clearly seen in Fig. if) of the drawings, The antifrictiiirl-collars 35 muy also be loi cated between the walls of the sernicollar, members 21 sind 22 and the antifrietionwheels ll). lbviouslv :i very.small amount i of lubriezition will be required to maintain the end ot' the journal or axle and the untiirietion devices cooperating therewith and the journal-box in the most. desirable condilion.
